Airbus A321-211, G-NIKO
The aircraft took off from Manchester Airport on a flight to Heraklion Airport, Crete. The sidestick control felt heavy as the PF rotated the aircraft and, after lift off, he noticed the Lowest Selectable Speed (VLS) indication on his Primary Flight Display speed-scale increasing. He reduced the aircraft’s pitch attitude and the airspeed increased. The aircraft was then able to resume a climb.
The Zero Fuel Mass (ZFM) had been used instead of the Actual Take Off Mass (ATOM) for the takeoff performance calculations before departure and the Flight Management System (FMS) had been programmed with the incorrect speeds.
